CC   -!- CATALYTIC ACTIVITY: ATP + 5-amino-1-(5-phospho-D-
CC       ribosyl)imidazole-4-carboxylate + L-aspartate = ADP + phosphate +
CC       (S)-2-(5-amino-1-(5-phospho-D-ribosyl)imidazole-4-
CC       carboxamido)succinate.
CC   -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway;
CC       5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from N(2)-
CC       formyl-N(1)-(5-phospho-D-ribosyl)glycinamide: step 4/5.
CC   -!- SIMILARITY: Belongs to the SAICAR synthetase family.
